If you are happy with your phone as is and going to REV A and having GPS enabled are not important to you then don't upgrade. There may be a problem with sprite backup after you upgrade but whatever "tweaks' or programs you have added I'm sure are available on this forum. If you do upgrade then you should consider upgrading further with one of the Roms available from some of the very talented and generous CHEFS. I was a total novice when I first joined, now although far from an expert, I change Roms frequently. My personal favorites are OMJ and Whosdaman but there are many others. searching can be a pain but if you ask, someone will usually help and not just tell you to search. I guarantee once you start trying the ROMS available here and you see how easy it is to do you will be hooked. Also, some of the CHEFS will make a custom rom for you for a small donation.
